A project's critical path is CDFGI. The expected time and the standard deviation of each activity are as follow

$\backslash$table$[[$Activity$,$A$,$B$,$C$,$D$,$E$,$F$,$G$,$H$,$I$],[\backslash$table$[[$Expected$],[$Time$]],2,5,8,6,4,9,10,1,5],[\backslash$table$[[$Standard$],[$Deviation$]],10,4,6,14,10,10,8,5,6]]$

What is the project standard deviation?
